SMD Inductors(Coils)

For Power Line(Wound)

VLP Series VLP4612

FEATURES

• This is an SMD power inductor for power supplies that has an

open magnetic path construction based on a low-height drum

core (upright).

• User terminals are contact-formed on the bottom of the drum

core using copper (finished with tin plating).

• It uses crosswise windings and supports large currents.

• It is lead-free compatible.

• With several variations in drum core height, users can choose

the perfect product for their application.

APPLICATIONS

• LCD modules

• Cellular phones

• Hard disk drives

Rated current:The rated current is the smaller of the values given based on the rate of inductance change (10% decrease from the initial value) or the

temperature rise (temperature rise of 40°C caused by the heat generated by the product itself). Please note that the current applied must be

DC.

• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific

bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.

• All specifications are subject to change without notice.
